“…Las cinco especies altoandinas evaluadas poseen la estrategia de acumular metales en las raíces, independientemente del nivel de contaminación del sustrato, esta estrategia es realizada por aquellas plantas denominadas fitoestabilizadoras (Hazrat et al 2013). Estas especies tienen la capacidad de reducir el transporte de los contaminantes al tallo y las hojas, y minimizando la movilidad de los metales pesados mediante la precipitación y la acumulación en las raíces (Alkorta et al 2004).…”

“…Total petroleum hydrocarbon and fatty acid methyl ester concentrations in soil were measured by Gas Chromatography–Mass Spectrometry (GC–MS), as described in Bartolomé et al [5] . Soil samples were used to determine the following microbial properties, as detailed in Galende et al [6] : (i) microbial activity was determined by basal respiration (BR) following ISO 16072 [7] ; (ii) potentially active microbial biomass was determined by substrate-induced respiration (SIR) following ISO 17155 [8] ; (iii) average well color development (AWCD) and (iv) number of metabolized substrates (NUS) were determined from Biolog EcoPlates TM following Epelde et al [9] . A root elongation bioassay with Cucumis sativus was performed to determine soil phytotoxicity.…”

Effectiveness and ecotoxicity of zero-valent iron nanoparticles during rhizoremediation of soil contaminated with Zn, Cu, Cd and diesel

et al. 2018

The remediation of soils simultaneously contaminated with organic and inorganic compounds is still a challenging task. The application of metallic nanoparticles, such as zero-valent iron nanoparticles (nZVI), for soil remediation is highly promising, but their effectiveness and potential ecotoxicity must be further investigated. In addition, the performance of nZVI when combined with other remediation strategies is a topic of great interest. Here, we present data on soil chemical (pseudo-total and CaCl2-extractable metal concentrations; petroleum hydrocarbon concentrations) and biological properties (microbial properties and phytotoxicity) after the application of nZVI to soil simultaneously contaminated with Zn, Cu, Cd and diesel, in the absence and presence of other remediation treatments such as the application of an organic amendment and the growth of Brassica napus plants. Soils were artificially contaminated with the abovementioned contaminants. Then, after an aging period of one month, nZVI were applied to the soil and, subsequently, B. napus seeds were sown. Plants were left to grow for one month. Soil samples were collected immediately after artificially contaminating the soil (T1), at sowing (T2) and at harvesting (T3). Overall, the application of nZVI had no effect on contaminant removal, nor on soil microbial parameters. In contrast, it did cause an indirect toxic effect on plant root elongation due to the interaction of nZVI with soil organic matter. These data are useful for researchers and companies interested in the effectiveness and ecotoxicity of zero-valent iron nanoparticles during the remediation of soil contaminated with metals and hydrocarbons, especially when combined with Gentle Remediation Options.

“…On the other hand, the application of organic amendments to soil, in addition to promoting plant growth and stimulating soil microbial activity, can sometimes result in a chemostabilization effect on some contaminants, thus hindering their degradation. This chemostabilization effect has nevertheless been more reported for toxic heavy metals [61].…”

Remediation of Organically Contaminated Soil Through the Combination of Assisted Phytoremediation and Bioaugmentation

et al. 2019

Here, we aimed to bioremediate organically contaminated soil with Brassica napus and a bacterial consortium. The bioaugmentation consortium consisted of four endophyte strains that showed plant growth-promoting traits (three Pseudomonas and one Microbacterium) plus three strains with the capacity to degrade organic compounds (Burkholderia xenovorans LB400, Paenibacillus sp. and Lysinibacillus sp.). The organically contaminated soil was supplemented with rhamnolipid biosurfactant and sodium dodecyl benzenesulfonate to increase the degradability of the sorbed contaminants. Soils were treated with organic amendments (composted horse manure vs. dried cow slurry) to promote plant growth and stimulate soil microbial activity. Apart from quantification of the expected decrease in contaminant concentrations (total petroleum hydrocarbons, polycyclic aromatic hydrocarbons), the effectiveness of our approach was assessed in terms of the recovery of soil health, as reflected by the values of different microbial indicators of soil health. Although the applied treatments did not achieve a significant decrease in contaminant concentrations, a significant improvement of soil health was observed in our amended soils (especially in soils amended with dried cow slurry), pointing out a not-so-uncommon situation in which remediation efforts fail from the point of view of the reduction in contaminant concentrations while succeeding to recover soil health.
